Beschreibung
Zusammenfassung:	A secondary battery includes an electrode body having an electrode plate, a rectangular exterior body housing the electrode body, a sealing plate, an electrode terminal provided on the sealing plate, a first current collector arranged between the electrode body and the sealing plate and connected to the electrode terminal, a second current collector arranged between the electrode body and a side wall of the rectangular exterior body and connected to the first current collector, and a tab group formed such that multiple electrode tabs extending from the electrode plate toward the side wall are stacked on each other and connected to the second current collector. The tab group is connected to the second current collector, and is bent on a connection portion side with the second current collector in parallel with the side wall. The curvature radius of a first rounded portion of a base portion of each tab is greater than the curvature radius of a second rounded portion of a tip portion of each tab.
